Using a Framework vs. Developing from scratch (pilanites.com)

I think it would be difficult to avoid using any framework and build everything yourself, but I guess the question is more on what the balance should be. I have found that when starting out a project where you don't have any existing code, you typically need to rely a lot more on existing frameworks. Over time, however, you realize which parts of your application are commoditized vs your core area of focus. You still may use external frameworks for your core stuff, but I have often found myself rewriting and replacing framework-based components as you need more optimization and customization.
